The Hirsch Observatory is located at Rensselaer Polytechnic Institute in Troy, NY, and has been serving students, researchers, and the public since 1942. (Weather in sidebar)

For the PublicOn Saturday nights starting in early February through mid-November, from 8 to 10, adults and children are invited to use the facility. If weather doesn't permit a good view, astronomy programs will be shown instead. See the Public Observing section for more information.

For the StudentsThe Rensselaer Astrophysical Society (RAS) is a Rensselaer Polytechnic Institute union-funded organization that allows students to pursue their interest in astronomy. The society works with the physics department to maintain the Hirsch Observatory.

Students are trained in the use of the Society's various telescopes, then placed on the observatory key list. Once on the key list, members can use the observatory any time. To learn more about the RAS visit their website.
